Patrones conductuales en el terrorismo actual: un análisis empírico

Resumen

El análisis del terrorismo, como campo distinto de investigation, es un fenómeno relativamente reciente. El estudio del Terrorismo ha sido un fenómeno de interés para las ciencias políticas, psicológicas, sociológicas centradas en el estudio de los fenómenos internacionales y la justicia criminal.

Este artículo es una revisión empírica y conceptual del Terrorismo. Es una aproximación conceptual y tipológica del fenómeno terrorista y de los fenómenos internacionales a través del análisis de las actividades terroristas y sus objetivos-estímulos.     

A unified approach to restricted games

There have been two main lines in the literature on restricted games: the first line was started by Myerson (1977) that studied graph-restricted games an the second one was initiated by Faigle (1989). The present paper provides a unified way to look on the literature and establishes connections between the two different lines on restricted games. The strength and advantages of this unified approach becomes clear in the study of the inheritance of the convexity from the game to the restricted game where an interesting result by Nouweland and Borm (1991) on the convexity of graph-restricted games is turned into a direct consequence of the corresponding result by Faigle (1989), by means of this relation. This revised version was published online in June 2006 with corrections to the Cover Date.     

Tipicidad de identidad de género y comparación intergrupal

Resumen

El objetivo de esta investigación era explorar, en grupos extremos en tipicidad de género, los niveles medio y subordinado sobre los que, según la Teoría de la Categorización del Yo de Turner y col., se construye el autoconcepto. Se han tomado dos grupos de sujetos: aquellos que establecen su identidad de género según los patrones típicos culturales (mujeres femeninas y hombres masculinos) y aquellos que la establecen con patrones culturalmente atípicos (mujeres masculinas y hombres femeninos). La hipótesis general de la que partía el trabajo ha sido que no existirían diferencias entre estos dos grupos en el grado de identificación con su endogrupo ni en la valoración de él, sino en la representación que tienen de la dicotomía hombre-mujer. Mediante un diseño factorial 2 x 2 (tipo de identidad: típica o atípica y sexo) se han analizado las siguientes variables dependientes: estereotipia de género, homogeneidad del endogrupo y del exogrupo, evaluación del endogrupo y del exogrupo, semejanza al endogrupo y al exogrupo. Los resultados confirman la hipótesis general. Se han encontrado diferencias entre los grupos con identidad típica y atípica sólo en estereotipia de género y en homogeneidad del endogrupo y del exogrupo. También se ha encontrado que existe relación entre estas tres variables.     

Attachment Styles and Self‐Image in Turkish Adolescents

The purpose of this article is to examine the attachment styles and the relation of these styles to the self‐image in Turkish adolescents. The study included 378 adolescents (196 females and 182 males) from high schools with different socioeconomic status (SES) who were administered Relationship Scale Questionnaires and Offer Self‐Image Questionnaires. The findings indicate that adolescents from a low SES had significantly low scores on self‐image scales compared with those from high and middle SES. It was found that secure attachment patterns affect social relationships and superior adjustment aspects of self‐image positively. The results of this study show that attachment patterns play an important role in the development of the self‐image, which is a crucial psychological structure gained in adolescence.     

Women,reindeer herding and the Internet: an innovative process in northern Sweden

This research note deals with an innovation initiative involving women, reindeer herding and the Internet. It shows how women reindeer herders from a Swedish Sámi village were a driving force in the development of several innovative, EU-funded projects focusing on information and communications technology. The article shows how the innovation initiative involved a wide range of actors, ascribing stakeholders from civil society important roles besides the public and private sectors. The innovation initiative involved several different strategies. One of these strategies was internationalization – both at the European and worldwide levels. This strategy was employed to prevent rigid political hierarchies blocking the prospects of gaining support from local and regional authorities. Another strategy was the continuous exchange of knowledge between engineers and potential end users, adapting the initiative results to the needs of the local context. As a result, the innovation initiative has produced several kinds of outcomes. It has generated new technology as well as economic and social benefits.     

A note on umvu estimation in the transformed chi-square family

The transformed chi-square family includes many common one-parameter continuous distributions. In that family, we give conditions under which a given function of the mean admits a minimum variance unbiased estimator and an orthogonal expansion for this estimator in terms of the generalized Laguerre polynomials. We show that such expansion is useful for obtaining bounds for the variance and for the study of the asymptotic properties of the unbiased estimators.     

Latino Acculturation and Perceived Educational Achievement: Evidence for a Bidimensional Model of Acculturation among Mexican-American Children

Considerable attention has been paid to the educational fate of Latino children and youths due to mounting evidence that their educational progress has been stagnant. This study investigates the effect of acculturation on perceived educational achievement among Mexican-American children, employing bidimensional acculturation theory to help explain acculturation patterns as related to both ethnic and mainstream identities. Using a sample of 294 Mexican-American children, five acculturation patterns were identified using cluster analysis. We found that the separated group of children had significantly higher educational achievement than the highly assimilated group. The study asserts that the segregated acculturation pattern can be protective for educational achievement of Mexican-American children within ethnically segregated environmental contexts.     

Affective state dependence in a recognition task

Resumen

Se ha elaborado un cuestionario sobre la evaluación del clima emocional (CE). El CE se concibe como un conjunto de emociones salientes y unas representaciones sociales sobre el estado actual y futuro de la sociedad (De Rivera, 1992). Su medida se realiza a través de agregados de respuestas individuales sobre la evaluación del clima social, durante un momento sociopolítico. Se presenta una investigación con estudiantes de 6 países. La escala de CE tiene coeficientes de fiabilidad y validez dimensional transcultural satisfactorios. Encontramos dos dimensiones básicas congruentes con las investigaciones sobre afectividad individual, con relaciones coherentes con afectividad, estrés post-traumático y afrontamiento de traumas colectivos. La no independencia de las respuestas fue contrastada mediante el coeficiente de correlación intraclase. Éste confirmó la interdependencia de respuestas intragrupal, lo) que constituye evidencia estadística de la existencia de un efecto de grupo. Este resultado justifica que se utilice la agregación de respuestas individuales (media por país) como un estimador de un constructo colectivo (CE). La media por país mostró asociación congruente con indicadores macrosociales. Las diferencias inter e intrapaíses en CE muestran la sensibilidad de la escala y su relación con el contexto social.
